Abstract Inco Limited has operated aluminum mine shaft conveyances since 1968. Aluminum conveyances are used where the hoisting system requires lightweight conveyances to maintain the hoist rope safety factors and mine hoist rope pulls as dictated by government regulations. Inco Ltd. currently has 20 skips (including spares) operating in the Ontario Division mines. The main problems encountered are with galvanic corrosion between dissimilar metals and metal fatigue. This paper will highlight some of the problems encountered and illustrate methods utilized to overcome the problems and improve the conveyances performance.
Keywords: Maintenance/Engineering, Hoisting systems, Corrosion, Conveyances.
